What should I do if the blue light from the screen hurts my eyes?

A: The issue of blue light should be viewed rationally. Harmful blue light mainly refers to high-energy short-wave blue light in the 415-455nm band. Long-term exposure may affect the retina. However, at present, the blue light output of mainstream mobile phone screens has been controlled within a safe range, and" "Blue light film" Usually, filtering blue light through dyeing can cause the screen to turn yellow and the picture quality to decline. A more scientific way to protect eyes is to reduce overall visual stimulation from both polarized light and reflected light. Woowhead Guanfudun does not rely on dyeing (it does not turn yellow), but instead softens the hard light of the screen through circular-polarized light and its own process to adjust the soft light standard, and reduces the reflectivity to below 0.5% in combination with magnetron sputtering AR coating. SGS has measured a light transmittance of 96.5% and a haze of 0.4%, with natural color reproduction. If blue light filtering is indeed necessary, it is recommended to use the system's built-in night view/eye protection mode instead of the tinted blue light film.
